A momentum conserving model with anomalous thermal conductivity in low dimension
Giada Basile, Cedric Bernardin, Stefano Olla
Anomalous large thermal conductivity has been observed numerically and experimentally in one and two dimensional systems. All explicitly solvable microscopic models proposed to dat…
Exploring the energy landscape of model proteins: a metric criterion for the determination of dynamical connectivity
Lorenzo Bongini, Roberto Livi, Antonio Politi +1
A method to reconstruct the energy landscape of small peptides is presented with reference to a 2d off--lattice model. The starting point is a statistical analysis of the configura…
Single-photon excitation of a coherent state: catching the elementary step of stimulated light emission
Alessandro Zavatta, Silvia Viciani, Marco Bellini
When a single quantum of electromagnetic field excitation is added to the same spatio-temporal mode of a coherent state, a new field state is generated that exhibits intermediate p…
Description of the nuclear octupole and quadrupole deformation
P. G. Bizzeti, A. M. Bizzeti-Sona
A parametrization of octupole plus quadrupole deformation, in terms of intrinsic variables defined in the rest frame of the overall tensor of inertia, is presented and discussed. T…
Giant isotope effect in the incoherent tunneling specific heat of the molecular nanomagnet Fe8
M. Evangelisti, F. Luis, F. L. Mettes +2
Time-dependent specific heat experiments on the molecular nanomagnet Fe8 and the isotopic enriched analogue 57Fe8 are presented. The inclusion of the 57Fe nuclear spins leads to a…
Topological conditions for discrete symmetry breaking and phase transitions
Fabrizio Baroni, Lapo Casetti
In the framework of a recently proposed topological approach to phase transitions, some sufficient conditions ensuring the presence of the spontaneous breaking of a Z_2 symmetry an…
